This question is being asked a lot these days, and the answer to it is critically important.

While all mainline religions claim to help their adherents to reach a higher level of some sort, Christianity claims an exclusivity unparalleled in any other religion. For Christianity professes that the fully divine + fully human Son of the one and only true God, Jesus:

became man and was born of the Virgin Mary

walked among us, teaching us the Truth

voluntarily died on a cross so that our sins could be forgiven

bodily rose from the dead, reopening Heaven for us

is still among us now

has given us the fullest deposit of His truth in His Catholic Church

is the one and only Savior of mankind

These are the foundational Truths of Christianity, and they leave no room for any other religion. For if you accept these core Truths, then you logically cannot accept the claims of any other religion.

And while the Catholic Church respects whatever goodness is in the other good religions, she rightfully declares that she is the one true Church started by Jesus (God) Himself. Only the Catholic Church has His fullest deposit of divine Truth, all of the seven Sacraments that Christ gave us, and the Apostolic Succession that enables her (& her alone) to trace all of her clergy back to Jesus’s Apostles.

In this day and age, society often sacrifices truth on the altar of “getting along”. But let us not forget that Jesus Himself said, “Do not think that I have come to bring peace upon the earth. I have come to bring not peace but the sword.” {Mt 10:34} Truth is by definition exclusive. Politically correct? No. But true? Yes.
